摘  要
模具生產(chǎn)技術(shù)水平的高低，已成為衡量一個(gè)國(guó)家產(chǎn)品制造水平高低的重要標(biāo)志。塑料工業(yè)的飛速發(fā)展，對(duì)注塑模具的設(shè)計(jì)與生產(chǎn)提出了質(zhì)量好、制造精度高、研發(fā)周期短等越來(lái)越高的要求，能否適應(yīng)這種需求已成為模具生產(chǎn)企業(yè)發(fā)展的關(guān)鍵因素。模具技術(shù)是融合機(jī)械工程、計(jì)算機(jī)應(yīng)用、自動(dòng)控制、數(shù)控技術(shù)等學(xué)科為一體的綜合性學(xué)科。
 隨著家電市場(chǎng)競(jìng)爭(zhēng)的白熱化，家電外殼設(shè)計(jì)成為了衡量家電外殼色彩、手感、精度的重要一環(huán)，進(jìn)而對(duì)設(shè)計(jì)提出了新的需求。本畢業(yè)設(shè)計(jì)正是從實(shí)際使用出發(fā)，進(jìn)行遙控器面蓋注塑成型模具的設(shè)計(jì)。遙控器面板注塑模具設(shè)計(jì)
 本設(shè)計(jì)是對(duì)遙控器面蓋進(jìn)行的注塑模型設(shè)計(jì)，利用Pro/E軟件對(duì)塑件進(jìn)行了實(shí)體造型，并對(duì)塑件結(jié)構(gòu)進(jìn)行了工藝剖析。首先對(duì)遙控器的結(jié)構(gòu)工藝性進(jìn)行分析，清楚了解塑件；由生產(chǎn)批量初步選定注射機(jī)型號(hào)；然后對(duì)本次模具設(shè)計(jì)的各個(gè)方案進(jìn)行論證分析，從選定方案中對(duì)澆注系統(tǒng)、成型工作零件的計(jì)算及校核，從中確定模架，推出與抽芯機(jī)構(gòu)的計(jì)算及校核，冷卻系統(tǒng)的計(jì)算及其水道布置設(shè)計(jì)，在最后對(duì)排氣和導(dǎo)向與定位結(jié)構(gòu)的設(shè)計(jì)。遙控器面板注塑模具設(shè)計(jì)
 其次利用注塑模具設(shè)計(jì)原理對(duì)各個(gè)具體系統(tǒng)零件進(jìn)行詳細(xì)的計(jì)算和校核，使設(shè)計(jì)出的結(jié)構(gòu)可確保模具可靠運(yùn)行，在此基礎(chǔ)上完成了本畢業(yè)論文的寫(xiě)作。最后繪制整套模具的裝配圖和零件圖。
 通過(guò)對(duì)本課題遙控器模型設(shè)計(jì)，我重溫了注塑成型與模具設(shè)計(jì)知識(shí)，使書(shū)本知識(shí)和理論與實(shí)際生產(chǎn)相結(jié)合，加強(qiáng)了對(duì)注塑模具設(shè)計(jì)知識(shí)的理解，使自己能運(yùn)用書(shū)本知識(shí)設(shè)計(jì)出基本符合生產(chǎn)要求的模具。在論文中我充分地運(yùn)用了大學(xué)期間所學(xué)到的知識(shí)。進(jìn)行了研究，鞏固和深化，達(dá)到了預(yù)期的設(shè)計(jì)意圖。

Abstract
 The technique level of molding tool which has became an important marking to measure the level of a national product. Some higher demands such as high quality, high precision, short time of R&D and so on were put forward since the rapid  development of plasticin dustry, whether they can adapt to these requirements has becoming an important factor for the development of molding producer. The mold technology is a comprehensive discipline that combines mechanical engineering, computer application, automatic control, numerical control technology and so on.
 As the competition in the appliance market growing, the appliance shell color, feeling and accuracy became an important part of the design and made new demands. This paper focus on the actual conduct and try to design remote control cover injection mold.      This design is the injection model of the remote control cover, use Pro / E software for the solid modeling plastic parts and analysis the structure of the process . Firstly, the structure of the remote control was analyzed to get a clear understanding of plastic parts.Then select the injection machine model by the initial production batch. Thirdly, analyze the various options,  select the program. The calculation and checking of the gating system and forming working parts determine the mold , put forward the core mechanism calculation and checking and confirm the calculation and channel layout of the cooling system .Finally, design the orientation and structure of the exhaust system .      Furthermore,we use the principle of the injection mold design to calculate and verify the various parts in details, so that the designed structure can operate reliablly .At last,draw the assembly and part picture for the whole set of the mold.Base on it, I write this paper.
 Thanks to the designing of this remote control mold , I review the knowledge of the injection molding and mold design and put the theory into practice.It also make me understand the knowledge of the injection mold design more,which can help me to use the book knowledge to design a mold matched the basic production requirement. In the paper, I make full use of the knowledge acquired during university to researching ,and achieve the desired intent.
 Key words: Injection mold   Drawing of patterns organization   Feed system  Cooling system
